said strip having an inner wall disposed between said boards and extending diagonally from the inner wall of one board to the inner wall of an adjacent board.

. 2. A corner element for concrete forms comprising a member having board receiving pockets in its edges, said member having an inner wall which extends diagonally between said pockets and from the inner surface of one board to the corresponding surface of an adjacent board.

3. A corner element for concrete forms comprising a strip of sheet metal having board receiving pockets in its edges disposed at right angles to each other, said metal strip having a Wall extending diagonally between said pockets from the inner surface of one board to the,inner surface of an adjacent board.

4. A corner element for concrete column forms comprising a strip of metal having its edge portions shaped to receive the edges of boards making up the complete form, said strip having an inner wall disposed between said boards and extending diagonally from the inner wall of one board to the inner wall of an adjacent board, and means for stifi'ening said strip of metal.

5. A corner element for concrete column forms comprising a strip of metal havin its edge portions shaped to receive the e ges of boards making up the com lete form, said strip having an inner wall disposed between said boards and extending diagonally from the inner wall of one board to the inner wall of an adjacent board, means for stiffening said strip of metal, said means having ears projecting from opposite ortions and overlapping each other and aving registering apertures, and a locking element engaging said apertures.
